Application filed May 25,

To all whom it may concern Be it known that I, ELTON F. KILBOURN, acitizen of the United States, Vresiding at Allerton, in the county ofIVayne and State of Iowa, have invented new and useful Imf provements inFarrowing Pens, of which the following is a specification.

This invention relates to improve-ments in farrowing pens, the generalobject of the invention being to provide a device which is adapted to beplaced in the vpen and which is so constructed that the small pigs cango into the same so'that they are protected from being injured by thesow and at the same time are kept warm.

Another object of the invention is to provide the device with heatingmeans and a detachable curtain for retaining the heat therein.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is a plank view ofa farrowing pen showing the invention in use.

Figure 2 is a sectionon line 2-2 of Figure 1.

Figure 3 is an enlarged side View of the l device itself, the curtainVbeing partly raised.`

Figure 4 is an enlarged plan view with parts broken away. ,c Figure 5 isa sectional detail view. Figures 6, 7 and 8 are views of a modified formof the device. Y

Figure 9 is a sectional detail view showing another means for fasteningon the cur tains. l

In these views A indicates the penl and B the device which forms thesubject matter of the invention. This device is formed of a framework 1which consists of the bottom part 2, the top part 3 and theuprightpieces 4 which connect the bottom and top parts together. Each of thebottom and top parts are composed of the triangular shaped pory tions 5and. the straight piece 6 Vwhich kis mar connected with the* apex of thetriangle.

Braces 7 may also be used wherever necessary.l VA cover 8, preferably ofoval-shape isfastened to the top part of the frame and this cover is ofgreater dimensions than the frame so that it will project well beyondthe frame. A curtain 9 is detachably con-Y nected with the edges of theycover, preferably by hooks and eyes 10 so that it may be detached whennecessary. Projections 11 are also placed on the edges of the cover toprevent the sow from lying againstthe device. A length of barbed wiremay be fastened to the cover in lieu of these rojec- A chamber 12 isformed in tie top of the frame under the cover for receiving `a hotbrick or a piece of soap stone, so thatV the interior of the device canbe heated. The curtain will hold this heat in the device.

The device is placed inthe pen in such a position that the sow can makeher bed alongside of the device. Thus the pigs can remain under thedevice and thus the dan- VYger of the sow crushing the pigs is removed.lThe sharp projections on the device will Yprevent the sow from lyingdown with her back to the device so that the pigs can readily feed. Whenthe weather is not cold the curtain can be removed.

' In the modification the frame 1 is made of triangular shape and thecover 8 is of substantially circular shape butin other respectsthisvform of the invention is similar to that before described. Y

In both forms'the device is rmly held in thepen by a polev13 whichpasses through the hole 14 inthe cover and hasits ends secured to thefloor of the pen and a cross piece or rafter at the top of the pen.

Figure 9 shows the curtain as being held in place by a wire clampingring 15 which passes through a loop 16 formed in the curtain.

The device is placed in the center of the pen so that the sow may passaround it and the device will prevent theO sow from walking over thepigs or lying down upon them. The curtain is not put in place untilafterV the sow has made a bed yas otherwise she might pull the curtain4off to use it as part of her bed. Y

' It is thought from the foregoing description that theadvantages andnovel features of my invention will be readily apparent.

vI. desire it to be understood that I may make changes in theconstruction and in the `in the scope of the appended claim. t

What I claim is p Y In combination With a farrowing pen, an

` open framework placed therein and consisting of upper and lowermembers and upright pieces Connecting the members together, a coverplate supported on the upper member and projecting beyond the Same so 1othat the pigs can pass under the same :md through the framework and adepending curtain connected With the edge of the cover.

In testimony whereof I affix my signature.

ELTON F, KILBOURN.
